Like many universities around the world, the University of Edinburgh has pledged to cut carbon emissions. As The Guardianreported, the university has concluded that the only way to reach its targets is to move beyond such straightforward measures as redesigning buildings for more efficient energy use. The university is now asking students and faculty members many personal, detailed questions to develop strategies on such issues as how many conferences faculty members use air travel to attend and what students eat. The use of videoconferencing instead of air travel, lower consumption of meat, and other measures are being discussed. One delicate issue is the calculation that international students -- due to air travel -- have a significant impact on total carbon emissions.
